Application filed June 29, 1928, Serial No. 28937 and in Great Britain November 11, 1927.

This invention relates to the manufacture of justifying spacers or spacebands such as are used in the typographical composing and casting machines known commercially under 5 the trade mark Linotype, and kindred machines, for the justifying of composed lines of matrices prior to the casting operation. It has for a principal object so to con struct these devices as to render unnecessary much of the delicate machining and fitting which has been inherent in the manufacture of similar devices as heretofore practised, and as a consequence thereof, to correspondingly reduce the cost of production.

The spacer or spaceband (which is hereinafter referred to as a spacer only), is, as ordinarily, formed of two main parts, viz: two oppositely wedge-shaped members, one shorter than the other and known as the sta tionary part and provided with cars by which it is held against moven'ient during justification, and the second or longer member which is slidably connected to the shorter one in such manner as to enable it to be forced upwards through the composed line for effecting the justification.

Hcretofore the guidance of the two members or wedges one on another has been exercised by mutually contacting inclined or dovetail surfaces, the satisfactory production of which has involved expensive machining and skilled manual labour.

in a spacer according to the present invention, the just-named surfaces are dispensed for effecting the necessary guidance canbe produced by simpler means and with little or no skilled labour, as will he readily'appreelated from the following detailed description and the drawings referred to therein.

Iln these drawings, which represent one of the improved spacers on a greatly enlarged with, and the surfaces which are reli d upon other, the faces represented being those seen in Figure 1, and t Figure 7 is a longitudinal section on line i of Figure 6.

1 indicates the before-mentioned shorter wedge and2 the longer one, both of which are secured together in relatively slidable connection, and the shorter of which is, as ordinarily, provided with ears 3 by which it is held against vertical movement during justification.

he longer wedge 2 has formed in it a longitudinal central recess 4c, whose two sides r boundaries 5, as shown best in Figure 4-,

are perpendicular to the planes of thetwo side faces of said wedge, and constitute surfaces which serve to guide this wedge during its movement on the companion wedge 1. Centrally within the recess d there is provided a tongue 6 on either side of which is a longitudinal slot bounded on the outer side by one of the aforesaid guiding surfaces 5, the said tongue at its lower end being free of, and terminating at a short distance from, the main body of the wedge 2.

The stationary wedge. 1 is so shaped as to permit the inclined surfaces (say at the front) of the adjustable wedge 2, to slide in contact with its own outer margins, and the oppositely directed or back surface of the tongue 6, as shown in Figure 4, to slide in contact with the central or sunk part of the wedge 1, offset shoulders 7, Figure 5, on'this last-named wedge, serving to provide the necessary guidance for the before-mentioned guiding surfaces 5 of the wedge 52. v 7

The tongue 6 preferably is integral withthe wedge 2 at its upper end and at its lower end provided with an enlargement or head transversely perforated as at 8, Figures 6 and 7,

for receiving a pin 9 which will also extend through axially alignedholes 1Q in the wedge 2; the head also serves as a stop for limiting the movement of the wedge 2 relatively to the wedge 1, and vice versa When the two wedges l, 2, are to be assembled, the tongue 6, then free at its lower end, is pressed outwards from the commonplane of the wedge 2, so as to enable the deflected middle part of the wedge 1, to he slipped beneath it into the recess l, after which the pin 9 is inserted throughthe holes 8 and 10, for

retaining thetongue and Wedge membersin permanent Working relationship, the said pin, it necessary, being riveted over at its outer ends to prevent displacement.

;A considerable economic advantage secured by the-aforesaid construction is the i11 terchangeability as between corresponding parts of different spacers, inasmuch as a damaged member of one spacer can be readily substituted by an undamagedcorresponding member of another spacer.

Instead of thetongue 6 being'integral with -the 'Wedge 2, as has been hereinbefore described as the preferred arrangement, it may be otherwise attached to t,but Whatever be "the constructionadopted, for the'purposes of 7 this inventionpthe tongue is regarded as a, limb or permanent member of the longer or movable Wedge.

Having described my invention, I declare that What I claim and desire to secure bylietters Patent is j 1. In a justifying spacer, the combination With a relatively stationary wedge, of'a movable co operating wedge slid-ably connected. thereto, a recess in'tlie movable wedge, a
